Question

for the same angle of incidence the angle of refraction in three different media A,B and C are20 ,30 ,and 40 .in which medium the velocity of light is maximum?

​

Answer 1

Explanation:

Since the angle of Incidence is same and medium from which light is entering, we can draw a relation. Greater the angle, less is the density of the medium and hence greater is the velocity light. Thus, velocity of light is maximum in the medium in which the angle of refraction is 40°.
